Hysteria, also known as hysteria, is the transliteration of hypsteria. It is a common mental disorder with a variety of clinical manifestations, so some people call it a “disease mimic”. It is a group of disorders caused by obvious mental factors, such as life events, internal conflicts or emotional excitement, suggestion or self-referral, etc. It is manifested by acute transient mental disorders, physical disorders (including sensory, motor and vegetative dysfunction), which have no organic basis. The etiology is mainly psychological and genetic, but people with hysterical personality characteristics such as emotional, suggestive, self-centered, and fantasy-rich are susceptible to hysteria. The main symptoms of hysteria: ① Hysteria somatic disorder (transformational hysteria). The symptoms are numbness, sensory hypersensitivity, sudden blindness, sudden complete hearing loss; loss of voice or laryngeal obstruction; limb paralysis, inability to stand or walk, but no muscle atrophy; spasmodic seizures, falling to the ground, convulsions, often hand and foot dancing, sometimes pulling hair, biting clothes. ② Hysterical psychological disorder (dissociative hysteria) manifests as sudden emotional outbursts, crying and laughing, head banging, hair pulling, clothes biting, chest pounding, rolling all over the floor, often accompanied by a dramatic change of mood and dramatic performance. Other patients with psychogenic amnesia may selectively forget the trauma-related contents or a certain stage of experience; patients with dysthymia may suddenly leave the activities of the plateau and go out to roam for several days. Since hysteria is a neurological disease, sometimes it is difficult to figure out, and there is no organic lesion, so many people think that hysteria is an evil disease, haunted by ghosts and gods, etc., and seek help from false doctors and gods everywhere. Not only are they cheated out of their money, but they also often cause their condition to worsen and delay normal treatment. If you or someone close to you appears similar performance and visit the doctor but find no problems with the examination, you should consider this disease, need to go to a psychiatric or psychological specialist in a timely manner!
